PCS-985GI is a high performance numerical generator protection device, which integrates main and backup protection into one device. It provides complete protection of a generator in power plant, and it also provides basic protection of a generator and an excitation transformer. PCS-985GI can be applied for turbo-dynamo generator, gas-turbine generator, hydro generator and nuclear power generator with different connection modes. PCS-985GI provides up to 56 analog input channels including current and voltage inputs. The generator protections are configurable. Ancillary functions of fault diagnostic, disturbance records, event records and communication function are integrated in the device. • Fault detector (FR) • Voltage and current drift auto adjustment • VT circuit supervision (VTS) • CT circuit supervision (CTS) • CT saturation detection (CTS) • Self diagnostic • GPS clock synchronization • Fault recorder • IEC61850 MMS & GOOSE for station bus • IEC60870-5-103 protocol • MODBUS protocol • DNP 3.0 protocol • Differential protection (87ET) • Overcurrent protection (50/51P)
